Definitions

  • the present invention relates to an apparatus and method for inducing emotions, and more particularly, to an apparatus and method for inducing emotions, wherein biosignals from a user are fedback and thus an emotion desired by a user can be accurately induced in accordance with the fedback biosignals.
  • An emotion generally means a mental state that is expressed as a change in feelings and a change in physiological activation due to an internal or external stimulus.
  • positive emotions such as love, ecstasy, satisfaction, or kindliness
  • negative emotions such as sadness, anger, fear, or disgust.
  • the emotion induction theories will be described in more detail.
  • the James-Lange Theory states that a bodily change does not occur due to the emotion, but it first occurs in a certain situation and then a particular emotion is induced upon cognition of such bodily change. That is, it is asserted that tears are not shed due to sadness, but the sadness is felt since the tears are shed.
  • the Cannon-Bard Theory states that after the central nervous system cognizes the emotion in response to the internal or external stimulus and a physiological response of the autonomic nervous system is then induced.
  • emotion induction methods for attempting prevention and treatment of various diseases, skin care, metabolism adjustment and psychological stability are widely performed in various fields by inducing positive emotions in a user using music, fragrance, images or the like based on such emotion induction theories.

  • this psychotheraphy apparatus is operated in such a manner that the patient presses down buttons based on his/her own subjective determination to ultimately control the visual and auditory stimuli, there is a problem in that it is impossible to objectively confirm as to whether a desired emotion is properly induced based on the visual and auditory stimuli.
  • U.S. Patent No. 5,725,472 discloses a psychotheraphy apparatus wherein physiological responses of a patient and push-button responses of the patient to asked questions are monitored to cognize an emotion induction state and then visual, auditory, olfactory, and tactile stimuli are selectively controlled based on the cognized emotion induction state, thereby resulting in new emotional, psychological and cognitive response patterns in the patient, as shown in FIG. 2.
  • this psychotheraphy apparatus is operated in such a manner that in order to ensure an accuracy of determination of emotion induction, the physiological responses of the patient is used only as auxiliary data for the determination of the emotion induction and the emotion induction state is cognized based on the button answers of the patient to the asked questions, there are problems in that it is difficult to objectively induce an emotion if the patient's responses are not clear, and that the patient's feelings cannot be naturally transmitted to the psychotheraphy apparatus since the patient should make an artificial effort to press down the buttons for expressing the patient's feelings.
  • the psychotheraphy apparatus has a limitation in that there is no specific suggestion regarding how to use the monitored physiological responses of the patient in the emotion induction.

  • the emotion induction control unit 31 checks whether the user has reached the desired emotional state based on the deviations D (d 0 , d 1 , d 2 ) of the increase/decrease patterns of the respective bioparameters (S160). If all the values of d 0 , d 1 and d 2 are 0, this means that all the bioparameters are increased and decreased in the same way as the bioparameter change models. Thus, it is determined that the user has reached the desired emotional state. If not, it is determined that the user has not reached the desired emotional state.
  • the emotion induction control unit 31 recognizes that the user has reached the desired emotional state when the user presses a satisfaction button, and then, terminates the emotion induction process.

  • the emotion induction control unit 31 checks whether the increase/decrease patterns of all the bioparameters do not conform to the bioparameter change models (S170).

Thus, the emotion induction control unit 31 changes the contents of the emotion induction protocol (S180).
  • the reason that the contents of the emotion induction protocol is caused to be changed is that the disagreement between the increase/decrease patterns of all the bioparameters and the bioparameter change models means that the current contents of the emotion induction protocol are inappropriate for the emotion induction since the user's cognition of the contents through cognitive action of his/her brains results in a change of the user's emotional state and thence changes in the values of the respective bioparameters.

  • step S170 if there is a bioparameter of which the increase/decrease pattern conforms to the bioparameter change model in step S170, it is checked whether an increase/decrease pattern of only one bioparameter does not conform to the bioparameter change model (S190). If two of the values of d 0 , d 1 and d 2 are 0, this means that only one bioparameter is increased and decreased differently from the bioparameter change model. Thus, the bioparameter is selected as a bioparameter to be changed and then the level of the selected bioparameter in the emotion induction protocol is increased or decreased by one grade (S210 and S220).
  • the value of the deviation d 0 , d 1 or d 2 of the increase/decrease pattern of the selected bioparameter is 1, this means that the increase/decrease pattern of the bioparameter is in a decreased state as compared with the increase/decrease pattern of the bioparameter change model.
  • the value of the bioparameter should be increased. Accordingly, the level of the bioparameter in the emotion induction protocol is increased by one grade.
  • the value of the deviation d 0 , d 1 or d 2 of the increase/decrease pattern of the selected bioparameter is -1, this means that the increase/decrease pattern of the bioparameter is in an increased state as compared with the increase/decrease pattern of the bioparameter change model.

  • the biostimulation module 50 outputs the physical signals for applying the visual, auditory, olfactory and tactile stimuli to the user's body, based on the emotion induction protocol in which the level has been increased or decreased.
  • the kind of the changed contents be temporarily stored. In such a case, it is possible to prevent identical contents from being selected when the contents may be changed again next time.
  • the level of the bioparameter in the emotion induction protocol in step 220 is increased or decreased by one grade, the kind and level value of the bioparameter be temporarily stored.
  • the emotion induction can be accelerated by increasing or decreasing the level of the bioparameter in the emotion induction protocol beyond or below the temporarily stored level value. For example, in a case where the level value of the SCRM in the emotion induction protocol is increased to 1, the bioparameter SCRM and its level value of 1 are temporarily stored.
  • the level value of the SCRM in the emotion induction protocol is increased to 2 with reference to the temporarily stored level value so that a stronger stimulus is outputted to the user's body, thereby accelerating the emotion induction.
  • the process further comprises the step of informing the user of the application of the changed emotion induction protocol before the application thereof, i.e. before the physical signals for stimulating the user's body are outputted according to the changed emotion induction protocol (S230).
  • S230 changed emotion induction protocol
  • the emotion induction control unit 31 calculates differences in changes of the bioparameters before and after the output of the physical signals for stimulating the user's body, extracts the increase/decrease patterns of the respective bioparameters, compares the increase/decrease patterns with the bioparameter change models, and extracts the deviations D (d 0 , d 1 , d 2 ) of the increase/decrease patterns of the respective bioparameters from the bioparameter change models.
  • the emotion induction control unit 31 determines that the user has not yet reached the desired emotional state. Further, since the increase/decrease patterns of the two bioparameters SCRM and HRV do not conform to the bioparameter change models, the emotion induction control unit 31 sets the SCRM as a bioparameter to be changed in accordance with the priorities shown in FIG. 9, and then upgrades the level in the protocol for the SCRM shown in FIG. 6c by one grade and thus selects a protocol having a level value of 1, i.e. a protocol in which the illumination is set to pink, the fragrance is set to juniper, the temperature is set to 27 °C, and the humidity is set to 75 %.
